closed the Euripus. Diodorus Siculus, i. 33, thus speaks of this same work.
Darius the Persian left the canal unfinished, as he was informed by some persons, that by cutting through the isthmus he would be the cause of inundating Egypt; for they pointed out to him that the Red Sea was higher than the level of Egypt. The second Ptolemy afterwards completed the canal, and in the most convenient part constructed an artfully contrived barrier, (
διάφοͅαημα,) which he could open when he liked for the passage of vessels, and quickly close again, the operation being easily performed.
The immediate communication therefore between the sea and the canal was cut off by a lock; and as there must have been two, there would be a flux and reflux of water between them on the passage of vessels. This probably suggested to our author the word Euripus, and is to be understood as applying to that portion of the canal included between the locks. By the word Euripus is generally understood the channel between Negropont and the mainland, which is subject to an ebb and flow of the sea. The storing up of water, and the distribution of it for the purposes of irrigation, was no doubt well known to the Egyptians. Diodorus, b. i. 19, ascribes to Osiris the invention. “Osiris confined the Nile by embankments on both sides, so that at the period of its rising it might not inconveniently spread over the country, but that, by gates (
διὰ θυοͅῶν) adapted for the purpose, the stream might be gently discharged as occasion required.
